General Description

The NAFE11388 is a highly configurable industrial-grade multichannel universal input analog front-end (AFE) that meets high-precision measurement requirements.

The device integrates low-leakage, high-voltage (HV) fast multiplexers, low-offset and low-drift programmable gain amplifier (PGA) and buffers, high data-rate 24-bit Delta-Sigma analog-to-digital converter (ADC), and low-drift voltage reference.

All of the HV analog pins are diode-protected internally for electromagnetic compatibility (EMC) and miswiring scenarios.
